I have a few questions.

#1) A little over a 1/4 through the video he adds a fractal node to the bump and chooses 'altitude'.  He adds another fractal node then a blender and chooses 'altitude' again.

I don't get these choices at all.  I have Vue6Infinite.  After I finish making my material it is not quite the same as his in the video.  I have to lower my bump size in the advanced material editor...he has 30, I have to have 15 to get a similar effect but then the shape is more round.

#2) Under bump in the advanced material editor, he has 'dependent on slope' under displacement mapping.  I don't have that choice.  How can I get the same effect and why don't I have the same options?

Thanks, Nancy
